I had the mirena fitted about 1 year ago after birth of dc2. I'm still breastfeeding so think this has helped fend of periods but over the last 3 months I've had breakthrough bleeding every 10 days ish, this matches with me having a horrid temper or wanting to to cry all the time, which is totally unlike me. Everything else n life good so don't really understand these random mood swings. Anyone else had a similar experience?
